The tool shown in 2 is int't. j decarbonizing the greater part 01? while the tools shown in Figs. 2 intended for ti'vuttngthe angles positions not so ensity accessible tool shown in Fig. 2. In Fig. 5 the free portion of flexible shaft (Z, carrying the tool a, is shown mounted upon a casing i, containing bevel gearing such as is commonly adopted in connection with dental drills. After the surfaces have been treated with tools such as shown in Figs. 2 to S Hwy may he finished or burnished with a round nosed tool such as shown in Fig. 1.

If desired the casing (1, may he held or supported at its end adjacent to the'uncovereov end of the shaft (Z, and in order that the vibratory action may be varied, this end of the casing 6, may be titted with a sliding: sleeve 01' be otherwise rendered adjustable in order that its position in relation to the tool at, or the length of the uncovered portion of the shaft 1/, may be varied to alter the vibratory action of the tool.

It will he understoml that the invention is applicable for other surfaces than those above mentioned, for instanee,it may he applied to the cleaning of tubes, the form of the tool. on the free end oi the nine strained portion of the shaft being varied to suit the nature of surfaoe to be treated.

Claims 1. A device of the character described comprising a. flexible shaft, a handleon said shaft, a hammer directly and rigidly secured to the free end of said shaft, said hammer having an unbalanced portion to one side of the center of the shaft, and means to rapidly rotate said shaft to produce a series of suc t-essive blows on the surface being operated 0n.

In a device of the character described comprising a flexible shaft, an unbalanced hammer directly and rigidly secured to the free end of the shaft, and a handle on the flexible shaft.
